If we alter setup.py to pin galaxy-importer, we should run package=galaxy-importer make requirements/pip-upgrade-single-package to pin it in the requirements files also.

Also, we need to patch the ldap compose profile to set the ulimits to make sure the service comes up correctly ...

With those two changes, all the ldap tests are passing for me locally.
